Best Train Horn For Truck

Power, Control, and Portability

BossHorn combines a high-output air compressor, real metal train horn trumpets, and our custom control PCB to give you the loudest, most reliable portable system. The PCB enables three selectable volume levels, motor overheat protection, and battery deep-discharge protection. Use your tool-brand battery (DeWalt, Milwaukee, Ryobi, etc.) or buy a full kit. With wireless remote range up to 2,000 feet and hand-assembly in the U.S., this setup is engineered for straight-up performance in real-world truck use.
